摘要
由于高分辨率遥感应用需求增加的牵引,国内外发射了越来越多的光学遥感卫星载荷.然而,随着传感器分辨率的增加,大气对地表信息干扰的问题也越来越突出,光学遥感图像的大气校正问题,因载荷特点和应用需求的改变面临着一些新的挑战,有必要对其进行总结和分析.本文在介绍大气校正现状和原理的基础上,按照光学遥感卫星大气校正输入信息来源不同,把大气校正方法归纳为基于图像和图形处理方法、基于辐射传输计算、基于图像自身信息反演大气参数、基于大气同步校正仪的大气校正4类进行介绍.最后,结合我国高分辨率光学卫星的发展方向,对当前的大气校正应用方案和未来发展进行了讨论和展望.
Driven by the demand of high resolution remote sensing applications,many optical remote sensing satellites with higher spatial resolution have been launched.But the extraction of the surface information from satellite image is also more and more affected by the worse atmopsheric conditions with the increase of sensor resolution.The atmospheric correction of optical remote sensing images is facing new situation and challenges due to new payload characteristics and upgraded application demands.Therefore a brief summary with simple analysis of the atmospheric correction methods is valuable.This paper introduces the current status and principle of atmospheric correction methods for optical remote sensing. According to the different approaches obtaining atmospheric parameters,these methods are classified into four catalogues,including the image graphical processing,the radiative transfer computing,the atmospheric parameters inversion from own-image,and the synchronous atmospheric corrector methods. At the end of this paper,with consideration of the development of Chinese high resolution satellites,the application status of atmospheric correction and future developments are discussed.
